I installed Ubuntu on my Chromebook Pro, and I’m getting a weird charging behavior.
If I plug in the USB-C charger the laptop will charge slowly, ~7 hour to full charge. If I suspend with the cable plugged in, It will charge fast ~1hour to full charge.
If I unplug the cable and plug in again I will be back to slow charge ~7hrs to full. Again, suspending and coming back will fix this.
Does anyone have an idea of what can be happening or what changes after suspending?
Just noticed this also happens with my pixelbook running Linux Mint. Is anyone else experiencing this?
I updated the mr chromebox firmware and now it’s always slowcharging on pixelbook 
On closer inspection, it looks like the charging behavior has been inverted, when the Chromebook Pro or Pixelnook is turned on or restarted, it is quick charging, the cable can be plugged and unplugged and it always quicharges.
However, if the computer is put to sleep and awakened, it will always slow charge no matter what until reboot.
This is a bit worse than before since now getting quickcharge needs a reboot. This happens on both Caroline and Eve on the latest firmware.
charging is completely controlled by the EC and the OS. The EC firmware on these devices hasn’t changed in 5+ years. coreboot has nothing to do with it.
I see, the change was immediate after updating to the latest firmware on both laptops, is there anything else I can try or is there a way to revert to the previous fw?
that’s why the script allows you to back up at any time and flash “custom” firmware
I see that, but I can’t find the previous one anywhere. I should have made a backup but I didn’t
